VAPOR-BURNER.

Patented Apr. 21, 1914.

Application filed November 22, 1912. Serial No. 732,889.

To all whom it may concern:

Be it known that I, HARRY OFFENBAOH, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented new and useful Improvements in Vapor-Burners, of which the following is a specification.

This invention relates generally to an improvement in vapor burners for hydrocarbon fuel being more specifically directed to simplify the construction of the spreader to facilitate the assembling of the parts and decrease the initial cost of manufacture.

The main object of the present invention is the provision of a spreader head for hydrocarbon burners of an otherwise useful type which head is so constructed as to materially simplify its manufacture and assemblage of the burner proper to materially decrease the cost of manufacture without in any way impairing the efficiency of the burner.

The invention in its preferred form of details will be described in the following specification, reference being had to the accompanying drawing, in which Figure 1 is a perspective view of the improved burner. Fig. 2 is a detail perspective view of the head disconnected. Fig. 3 is a horizontal section of the head. Fig. 4 is a transverse section on line 4 4 of Fig. 2.

Referring particularly to the accompanying drawing, the improved burner comprises a threaded nipple 1 for the connection of the burner to a supply pipe (not shown), from which nipple rise divergent oil supply pipes 2 designed to be connected at their upper ends to the retort head 3, and from which head depends the gas pipe 4 of a U-shaped connector centrally formed within the plane of the pipes 2 with a jet nozzle 5 in open communication with the pipes 4.

The head 3 which forms a material part of the present invention is preferably constructed by casting or otherwise and has an integral body including a concavo-conveX disk portion 6 in the concaved depression of which is formed diametrically arranged ribs 7 disposed at right angles to each other and having enlarged circular terminals 8. The head is completed by coring the respective ribs longitudinally, said coring 9 extending through the full lengths of the ribs and through the enlargements 8, which enlargements, it will be understood, extending downwardly through the disk 6 depend from the convex side of the disk. The enlargements are then cored vertically for the reception of the respective ends of the pipes 2 and 4, and the terminals of the cores 9 beyond the vertical bores of the enlargements are brazed closed. In this construction communication is provided by the bores of the ribs from one set of pipes 2 through the head to the remaining pipes 4:, it being understood that the respective pipe sections are seated and secured in gas-tight manner in the vertical bores of the enlargements. In this form of head it is obvious that the corn pletion of the same from the initial casting is a simple matter of boring and brazing and that the complete necessary communication between the pipes of the burner is accurately provided and the convex face of the disk serves as an effective spreader. The head thus constructed is of comparatively insignificant cost as compared to the usual heads of vapor burners without in any way detracting from the complete efficiency of the burner. A flanged retaining ring 10 is brazed to the respective pipes 2 and 4 encircling the same below the head, to support a mechanical flame confiner forming no material part of the present invention and hence not illustrated or described.

What is claimed is i A retort head for hydrocarbon burners including a concave convex disk formed with diametrically disposed ribs in the concave portion with the upper surface of the ribs in a plane of the edge of the disk, the terminal ends of each rib being formed with enlargements coincident with the edge of the disk and projecting through and below said disk, the enlargements being bored vertically and the ribs bored longitudinally to form open communication between said enlargements and ribs, oil supply pipes communieating with a pair of diametrically opposed enlargements, and a gas pipe having its terminals communicating with the remaining pair of diametrically opposed enlargements.

In testimony whereof I aflix my signature in presence of two witnesses.

HARRY OFFENBACH.
